The Mountaintop Recreation Company – a division of California Land Management – operates campgrounds and day use areas on the San Bernardino National Forest northeast of Los Angeles. Most of the facilities are located on or near Big Bear Lake or Lake Arrowhead. Many are open for an extended season from April through November.
The prime jewel of these facilities is Serrano Campground located on the north shore pf Big Bear Lake. This campground is one of the most popular within the National Forest system and reservations are highly recommended.
